Description
Summary:One of the leading challenges of condensed matter physics in the past few decades is an understanding of the high-temperature copper-oxide superconductors. Although the d -wave character of the superconducting state is well understood, the normal state in the underdoped regime has eluded understanding. Here, we review the past few years of quantum oscillation measurements performed in the underdoped cuprates that have culminated in an understanding of the normal ground state of these materials. A nodal electron pocket created by charge order is found to characterize the normal ground state in YBa 2 Cu 3 O 6+δ and is likely universal to a majority of the cuprate superconductors. An open question remains regarding the origin of the suppression of the antinodal density of states at the Fermi energy in the underdoped normal state, either from mainly charge correlations or, more likely, from mainly pairing and/or magnetic correlations that precede charge order.
